CP 4: Wasco Viaduct

Edition: March 2021
Project: Wasco Viaduct

At the Wasco Viaduct, crews continue to set panels on the mechanically stabilized earth (MSE) wall on the north side of the structure. Crews continue to backfill with dirt to form the slopes of the structure. At the top of the northside of the structure, ironworkers are tying rebar to form the box girder section as well as the bent diaphragm and anchors of the superstructure.

At the pergola section, crews recently completed a utility relocation allowing crews to get to work on the center portion of the structure. Crews have placed concrete to form the columns for the center span.

Further south, precast panels continue to be installed to form the deck of the structure. Surveyor crews on top of the overhead portion over the BNSF right-of-way mark the necessary points needed to bring the Wasco Viaduct together. Just below on the edge girder, crews are working on the finishing of the exposed surface.
